A. O. Smith water purifiers are fully electronic control all models equipped with Filter replacement reminder, so the machine will remind user of replacing filter with sound and color when filter life is due. Faucet will also set reminder with corresponding color at the same time (only selected models).

The recommended filter life is based on the average indexes of tap water in various districts. If users’ actual water quality and using frequency have a great discrepancy with average index, actual filter life differs greatly from estimated time, such as early clogging or invalidity of filters. The customer should arrange for replacement with their local service center based on the machine’s actual usage conditions.

What is NFS/ANSI 58 and NFS/ANSI 42?

NSF/ANSI 58: Reverse Osmosis Drinking Water Treatment System.

NSF/ANSI 58 establishes the minimum requirements for the certification of point-of-use (POU) reverse osmosis systems designed to reduce contaminants that may be present in public or private drinking water.

The scope of NSF/ANSI 58 includes material safety, structural integrity, total dissolved solids (TDS) reduction and other optional contaminant reduction claims. The most common optional claims addressed by NSF/ANSI 58 include cyst reduction, hexavalent and trivalent chromium reduction, arsenic reduction, nitrate/nitrite reduction, and cadmium and lead reduction.

NSF/ANSI 42: Drinking Water Treatment Units – Aesthetic Effects

NSF/ANSI 42 establishes the minimum requirements for the certification of POU/POE filtration systems designed to reduce specific aesthetic or non-health-related contaminants (chlorine, taste, odor and particulates) that may be present in public or private drinking water.

The scope of NSF/ANSI 42 includes material safety, structural integrity and aesthetic, non-health-related contaminant reduction performance claims. The most common technology addressed by this standard is carbon filtration.
